How to lager beer without a fridge?

In this brief article, we will answer the question, “How to lager beer without a fridge?” and methods to chill beer as well as the yeasts that can be used to lager beer without a fridge.

How to lager beer without a fridge?

To lager beer without a fridge, take a large tub and fill it with water as well as frozen water bottles. The frozen water bottles have a slower melting capacity and would cool your beer pretty quickly.

You can also use old water bottles or juice bottles made of plastic for this purpose. Plastic would expand and not burst, unlike glass. Also, make sure to check whether your bottles have leaks or dents before you are planning to use them.

What temperature is required to lager beer?

You can lager beer at a temperature of 35 degrees Fahrenheit. At a temperature of 45 degrees Fahrenheit, fermentation can occur.

High temperature can increase the risk of your beer turning too fruity and extremely low temperature can cause the yeast to die.

A proper fridge or freezer is important to lager beer especially if you are planning to homebrew it.

It is better to avoid lagering beer at room temperature. This is because the beer can develop a really bad flavor if it is kept at room temperature for long.

Which yeasts can you choose?

Usually, lager yeasts would require a temperature at least below 50 degrees Fahrenheit. If you do not have a fridge or freezer and live in a humid area, choose yeasts that can thrive in warmer conditions.

Some of the yeasts that you can choose from are given below:

  • Wyeast 2035 American lager: This yeast can thrive at temperatures up to 48-58 degrees Fahrenheit.
  • White Labs WLP1983 Charlie’s Fist Bump Yeast: This yeast can thrive up to a temperature of 50-73 degrees Fahrenheit. 

It is usually recommended to ferment the wort at a lower temperature even if these yeasts can thrive at higher temperatures.

You can ferment yeast at a much shorter period if you use any of these yeasts. Make sure to avoid placing the yeast in an area prone to temperature fluctuations.

What are the other alternatives to lager a beer?

  • If you are using a cooler, you can add ice chips by placing them in plastic bags. These chips can also be reused and save you the mess of cleaning spilled water.
  • You can fill plastic or a tub bin with ice. Choose the one with wheels so that it would be easy to move them to the fermenter. To make the cooling process faster, you can place a wet towel on top of the bin along with a fan.
  • After the fermentation process is over, you can transfer the beer onto a bottle before you lager it. You can add the yeast and priming sugar and let the yeast do its work for 2-3 weeks. 

After 2-3 weeks, open and check the carbonation post which you can keep the bottle in the fridge after squeezing it a little. You can repeat the same process for other bottles.

In this method, sediments can form in the beer. You can filter out the sediments coming out of the beer.

  • You can try using a temperature controller to lager your beer. Temperature control devices can help in warming or cooling your wort.

An immersion chiller can also be placed in the fermenter. Opt for a stainless steel immersion chiller.

How to keep your beer chilled for a short while without a fridge?

  • If you are outdoors, you can place the beers near a natural source of water like rivers or streams. Secure the beer properly before placing them in water so that the beer does not flow away.
  • You can place the beer in ice water as well. The amount of ice and water present should be 50/50 or equal. 

The beer should be kept insulated and sealed properly. Into the ice water, you can add a little bit of salt as well. Salt can help in lowering the temperature of freezing.
